Preparations for Next Moonwalk Simulations Underway (and Underwater)
While astronaut Gene Cernan was on the lunar surface during the Apollo 17 mission, his spacesuit collected loads of lunar dust. The gray, powdery substance stuck to the fabric and entered the capsule causing eye, nose, and throat irritation dubbed “lunar hay fever.” Credit: NASACredit: NASA Moon dust, or regolith, isn’t like the particles on Earth that collect on bookshelves or tabletops – it’s abrasive and it clings to everything. Throughout NASA’s Apollo missions to the Moon, regolith posed a challenge to astronauts and valuable space hardware.
During the Apollo 17 mission, astronaut Harrison Schmitt described his reaction to breathing in the dust as “lunar hay fever,” experiencing sneezing, watery eyes, and a sore throat. The symptoms went away, but concern for human health is a driving force behind NASA’s extensive research into all forms of lunar soil.
The need to manage the dust to protect astronaut health and critical technology is already beneficial on Earth in the fight against air pollution.
Working as a contributor on a habitat for NASA’s Next Space Technologies for Exploration Partnerships (NextSTEP) program, Lunar Outpost Inc. developed an air-quality sensor system to detect and measure the amount of lunar soil in the air that also detects pollutants on Earth.
Originally based in Denver, the Golden, Colorado-based company developed an air-quality sensor called the Space Canary and offered the sensor to Lockheed Martin Space for its NextSTEP lunar orbit habitat prototype. After the device was integrated into the habitat’s environmental control system, it provided distinct advantages over traditional equipment.
Rebranded as Canary-S (Solar), the sensor is now meeting a need for low-cost, wireless air-quality and meteorological monitoring on Earth. The self-contained unit, powered by solar energy and a battery, transmits data using cellular technology. It can measure a variety of pollutants, including particulate matter, carbon monoxide, methane, sulfur dioxide, and volatile organic compounds, among others. The device sends a message up to a secure cloud every minute, where it’s routed to either Lunar Outpost’s web-based dashboard or a customer’s database for viewing and analysis.
The oil and gas industry uses the Canary-S sensors to provide continuous, real-time monitoring of fugitive gas emissions, and the U.S. Forest Service uses them to monitor forest-fire emissions.
“Firefighters have been exhibiting symptoms of carbon monoxide poisoning for decades. They thought it was just part of the job,” explained Julian Cyrus, chief operating officer of Lunar Outpost. “But the sensors revealed where and when carbon monoxide levels were sky high, making it possible to issue warnings for firefighters to take precautions.”
The Canary-S sensors exemplify the life-saving technologies that can come from the collaboration of NASA and industry innovations.

NASA Earth Observatory image by Lauren Dauphin, using VIIRS data from NASA EOSDIS LANCE, GIBS/Worldview, and the Suomi National Polar-orbiting Partnership The Suomi NPP satellite acquired this image of a plume of Saharan dust as winds lofted it over the Atlantic Ocean on Aug. 24, 2024.
The Sahara Desert is Earth’s largest source of airborne dust, and the particles can travel for thousands of miles. From late spring to early fall, it is common for the dry, dusty Saharan Air Layer to carry the particles westward across the Atlantic Ocean high in the atmosphere. Saharan Air Layer activity subsides after mid-August, according to NOAA, making it less likely that the plume shown here is bound for a transoceanic journey. Instead, it arcs to the north after blowing out over the ocean. Earlier in the summer, however, several clouds of fine dust from the Sahara reached the United States, creating hazy skies over Texas.

This artist’s concept depicts one of the Carbon Mapper Coalition’s Tanager satellites, the first of which launched on Aug. 16. Tanager-1 will use imaging spectrometer technology developed at JPL to measure greenhouse gas point-source emissions.Planet Labs PBC Developed by the agency’s Jet Propulsion Laboratory, the imaging spectrometer will provide actionable data to help reduce emissions that contribute to global warming.
Tanager-1, the Carbon Mapper Coalition’s first satellite, which carries a state-of-the-art, NASA-designed greenhouse-gas-tracking instrument, is in Earth orbit after lifting off aboard a SpaceX Falcon 9 rocket from Space Launch Complex 4E at Vandenberg Space Force Base in California at 11:56 a.m. PDT Friday, Aug. 16. Ground controllers successfully established communications with Tanager-1 at 2:45 p.m. PDT the same day.
The satellite will use imaging spectrometer technology developed at NASA’s Jet Propulsion Laboratory in Southern California to measure methane and carbon dioxide point-source emissions, down to the level of individual facilities and equipment, on a global scale. Tanager-1 was developed as part of a philanthropically funded public-private coalition led by the nonprofit Carbon Mapper. Planet Labs PBC, which built Tanager-1, and JPL are both members of the Carbon Mapper Coalition and plan to launch a second Tanager satellite equipped with a JPL-built imaging spectrometer at a later date.
“The imaging spectrometer technology aboard Tanager-1 is the product of four decades of development at NASA JPL and truly in a class of its own,” said JPL Director Laurie Leshin. “The data that this public-private partnership provides on sources of greenhouse gas emissions will be precise and global, making it beneficial to everyone.”
Once in operation, the spacecraft will scan about 50,000 square miles (130,000 square kilometers) of Earth’s surface per day. Carbon Mapper scientists will analyze data from Tanager-1 to identify gas plumes with the unique spectral signatures of methane and carbon dioxide — and pinpoint their sources. Plume data will be publicly available online at the Carbon Mapper data portal.
Methane and carbon dioxide are the greenhouse gases that contribute most to climate change. About half of methane emissions worldwide result from human activities — primarily from the fossil fuel, agriculture, and waste management industries. Meanwhile, there is now 50% more carbon dioxide in the atmosphere than there was in 1750, an increase largely due to the extraction and burning of coal, oil, and gas.
“The Carbon Mapper Coalition is a prime example of how organizations from different sectors are uniting around a common goal of addressing climate change,” said Riley Duren, Carbon Mapper CEO. “By detecting, pinpointing, and quantifying super-emitters and making this data accessible to decision-makers, we can drive significant action around the world to cut emissions now.”
The imaging spectrometer aboard the satellite measures hundreds of wavelengths of light that are reflected by Earth’s surface. Different compounds in the planet’s atmosphere — including methane and carbon dioxide — absorb different wavelengths of light, leaving spectral “fingerprints” that the imaging spectrometer can identify. These infrared fingerprints can enable researchers to pinpoint and quantify strong greenhouse gas emissions, potentially accelerating mitigation efforts.
Tanager-1 is part of a broader effort to make methane and carbon dioxide data accessible and actionable. That effort includes using measurements provided by NASA’s EMIT (Earth Surface Mineral Dust Source Investigation), an imaging spectrometer developed by JPL and installed on the International Space Station.

On July 19, 2024, NASA officially named Johnson Space Center’s building 12 the “Dorothy Vaughan Center in Honor of the Women of Apollo.” A portrait of Dorothy Vaughan is now the central feature at the entrance of the newly named building. This portrait was hand-painted by Eliza Hoffman, an accomplished artist who is also a recent graduate from Clear Creek Independent School District.
Recent Clear Creek Independent School District graduate and artist Eliza Hoffman hand-painted a portrait of Dorothy Vaughan in honor of the Women of Apollo. The handcrafted portrait of Vaughan took about a month to complete. The photo the Vaughan family wanted to use for the ceremony was black and white, so Hoffman had to brainstorm how to bring the photo to life in living color. This led her to search for colorized versions of the reference photo on the internet to guide her in the painting process. She revealed that she first learned of Vaughan from the movie “Hidden Figures,” which she was inspired to watch after reading the book “Women in Space” throughout her childhood.
When privately revealing the artwork to the Vaughan family, Hoffman felt their emotion and joy. She reflected, “I am honored to have the family of such a great woman be so moved by my painting. It is a memory that I will always remember.”
NASA’s Johnson Space Center Director Vanessa Wyche greets artist Eliza Hoffman at the surprise unveiling of Dorothy Vaughan’s painted portrait in the main hallway of the Dorothy Vaughan Center in Honor of the Women of Apollo.NASA/David DeHoyos Hoffman shared that “One of the great things about making art is that it communicates information about the subject and its emotion to the audience. In this case, I was given the chance to create a portrait which will help inform people for years to come about Dorothy Vaughan’s life and legacy.”
At the ribbon-cutting ceremony, it was noted to Hoffman that her portrait will now become a part of Johnson’s history. Through Hoffman’s research on Vaughan, she noticed that Vaughan was not only a person beloved by many but also a woman that walked with humility and gentleness, which she hopes viewers see in her painting.
